How do I disable jacoco-agent after jacoco:report?

Question

I have a maven-project, using "test"-phase as well as "integration-test"-phase. In the test-phase, JUnit-Tests are executed, in integration-test there are HTMLUnit-tests. I am using Jacoco[1]-maven-plugin in purpose to measure the codecoverage done by the JUnit-tests of my project. When doing integration-test, I am using maven-embedded-glassfish-plugin to start a glassfish-server and deploy my app before executing the tests.

Sad but true, I have to disable jacoco for time being, as it does not harmony with "integration-test"-phase.

Jacoco's report goal is / should be exceucted at prepare-package-phase, so I assume that it should not influence integration-test-phase. But when I enable jacoco:report, my integration-tests do not run any more because of memory-size problems[2].

How do I stop jacoco:report influencing the integration-test-phase?

Does your Class SACParserCSS21TokenManager have a very large method ? If your are close to the limit allowed for a method (which is very large, 64Kb), instrumentation code can push it over the limit. — Samuel EUSTACHI, Jan 28 '13 at 09:48
The class "SACParserCSS21TokenManager" seems to be used by project http://cssparser.sourceforge.net/ which seems to use http://www.w3.org/Style/CSS/SAC/ as an API. cssparser itself is a dependency of HTMLUnit¹ - I am using HTMLUnit 2.11. Hmmm, I can't proved find SACParserCSS21TokenManager-origin right now. ¹ http://htmlunit.sourceforge.net/dependencies.html — Markus Schulte, Jan 28 '13 at 13:41

Ok, so I see the problem.

The method jjMoveNfa_0 of class

http://grepcode.com/file/repo1.maven.org/maven2/net.sourceforge.cssparser/cssparser/0.9.5/com/steadystate/css/parser/SACParserCSS21TokenManager.java

is insanely long with 4203 loc. So the solution for you should be to avoid instrumentation on this class.

You can exclude package "com.steadystate", which includes the class, by telling the jacoco-maven-plugin to do so:

<plugin>
  <groupId>org.jacoco</groupId> 
  <artifactId>jacoco-maven-plugin</artifactId>
  <version>${jacoco.version}</version>
  <configuration>
  <excludes>
    <exclude>**com.steadystate*</exclude>
  </excludes>
  ...
</plugin>

Not the solution I had in mind, but at least it works. Thank you! – Markus Schulte Jan 29 '13 at 16:02
You're welcome, thanks for the edit, this is indeed what I was thinking about. – Samuel EUSTACHI Jan 29 '13 at 16:17

I'd like to add that in Gradle you have to add this to exclude com.steadystate: `test { jacoco { excludes = ["com/steadystate/**"] } }` – Marcin Jan 05 '15 at 12:21
